You say forgiveness is a paradox in that gift-giving aids the one who gives the gift. Yet, is there no correction of the other’s misbehavior?
To correct the other’s misbehavior is to engage in the moral virtue of justice. Forgiveness and justice should exist side-by-side. If you are being abused by someone, you can forgive if you choose to do so and you can and should seek fairness so that the other stops the unjust behavior.
